I'm trying to get and set variables in Matlab from IDL. Using an older
newsgroup posting of how to do this, I'm able to put an array created
in IDL into Matlab and see it in Matlab's workspace, but I'm getting a
"bad variable type" response from Matlab when I try to get the array
back into IDL. Anyone see what my problem is in the code below? Or, if
there's a better way to do
this that would be valuable information as well. This is with IDL 6
and
Matlab 6.5 R13. Many thanks.
IDL> oMatlab6=OBJ_NEW('IDLcomIDispatch$PROGID$Matlab_Application_ 6')
IDL> data=DINDGEN(100)
IDL> PLOT, data
IDL> oMatlab6->PutFullMatrix,'fromidl','base',data,data
IDL> oMatlab6->Execute,'plot(fromidl);'
IDL> fromMat = oMatlab6->GetFullMatrix('fromidl','base',zreal,zimag)
% IDLCOMIDISPATCH$PROGID$MATLAB_APPLICATION_6::GETFULLMATRIX: Unable
to
call method GETFULLMATRIX.
Bad variable type.
% Execution halted at: $MAIN$

Rob,
We *should* be able to figure something out for you. I'm fairly
certain the GetFullMatrix method returns a SAFEARRAY which is not
supported by the IDL 5.5 COM bridge - SAFEARRAY majority is the
opposite of IDL's storage.
I'd suggest we try using the MATLAB Engine which is a lower level C
API. Please contact me directly to discuss in more detail and then we
can share our findings with the group once we have tried a few things.
Thanks,
-Paul

Update: Anyone interested should contact RSI directly. A solution
does exist, but is not ready for general useage (yet). Also, would
like to gauge interest to justify whether or not a more complete
solution would be useful.
